I have a form (a string) that I want to process. The form can contain certain occurrences of this, for example: >>1244.

I need to grab every number after every occurrence of >>, but I'm not sure how. I'm thinking regex, but I'm terrible at it. I've read several similar questions, but the answers are wildly different, don't apply to this (they find the next WORD after a keyword) or sometimes use contradicting approaches.
